spi: clps711x: Remove duplicate code to set default bits_per_word and…

… max speed

In the implementation of __spi_validate(), spi core will set transfer
bits_per_word and max speed as spi device default if it is not set for
this transfer. So we can remove the same logic in spi_clps711x_setup_xfer() and
spi_clps711x_transfer_one().
